EMERGENCY FIRE EXTINGUISHER Filed April 17, 1957 2 Sheets-Sheet 2 IINVENTOR. MANL/O S/MO/VC/N/ 6 (AELOS FALCON United States PatentEMERGENCY FIRE EXTINGUISHER Manlio Simoncini and Carlos Falcon, BnenosAires, Argentina Application April 17, 1957, Serial No. 653,321 3Claims. (Cl. 169*35) The present invention refers to a fire extinguisherfor emergency purposes and more particularly to a manual instrumentwhich, in the manner it is presented for ready use, will solve one ofthe most serious problems created by the starting of a fire in cars, aswell as in homes and other establishments.

This is represented in a flagon made of elastic material Which containsan extinguishing fluid and is sealed through the head of the spout,which also serves to suspend the unit, so that it will always be foundin its place whenever an emergency arises; and since the suspensionsupport has cutting means precisely in the plane where the head ends,same support serves as guillotine for decapitating the flagon, openingit at the same time, so that it may be used without loss of time.

This means that the efiiciency of the device resides in itsinstantaneous use without any complications.

In this manner will be avoided the inconvenience of the known type ofapparatus which do not always respond to their opening mechanism andgeneral operation, precisely at the moment it is most required.

Apart from what has been stated above, several are the objects pursuedby the present invention amongst which may be stated the fact ofproviding a directional projector of fluid, so that the user may directthe jet towards .the principal centers of the fire, thus attacking indirect manner the fire from the very beginning.

Another object is that of obtaining with the flagon range of pressure,according to the needs in each case, so that the directed jet may reachheights or inaccessible places.

Another object of the invention is that of providing an apparatus withthe full load of fire extinguishing material at an economical price.

Another object is to provide a fire extinguisher, ideal for automobiles,where it will always be ready to avert any accidental disaster.

The further objects of the present invention will be shown throughoutthe following specification which for a greater clearness andcomprehension has been illustrated by several drawings in which:

Fig. 1 is a vertical section of the fire extinguisher set on the supportwhere it may be seen pending from its head, which is to be cut when theflagon is removed from the support.

Fig. 2 is a plan view showing the head of the flagon partially brokenaway to show the spout opener which in this case has a double knife in Vshape, so that when pulling the body, the head is lopped.

Fig. 3 is a graphic demonstration of how, when pulling the body, thehead set on the spout is cut by the knives, so that it may be instantlyused.

Fig. 4 shows the decapitation which permits the use of the flagonwithout loss of time.

Fig. 5 is an apparatus suspended in its support as in Fig. of beingtriangular, possesses movable blade by which the lopping is effected.

1 but with different lopping means, which instead Fig. 6 is a plan viewof Fig. 5. A

Fig. 7 is an elevational view of the apparatus graphically showing themanner of grasping the flagon, whilst with the thumb the knife isoperated, thus freeing the spout from the head, and finally Fig. 8 is aperspective view of the flagon in operation after its removal anddecapitation.

In the different drawings the same reference numbers are used for equalor corresponding parts, the different elements designated by letters.

As may be seen in the drawing, a is the support, the base 1 of which maybe fixed at any point or place in the house, motor car, etc., where thefire extinguisher is supposed to operate. 0n said support is mounted theflagon b which is made of an elastic or plastic material, such aspolyethylene, so that the fluid contents may be projected through itsspout 2 by manually squeezing the body of the container.

Spout 2 being hollow, is sealed by head 3, so that the whole flagon,such as it is provided from the manufacturer and while it has not beenused, is sealed from the air in order to contain the fire extinguishingfluid in good condition for an indefinite period.

The flexible head 3 is of a sufliciently small diameter to be forcedthrough opening 4 of support a, so that when said head has passedthrough the opening 4, it will remain as a button passed through abuttonhole, and since the section of the head 3 is larger than that ofthe opening, same will act as retaining means so that the flagon will besuspended in pending position (Figs. 1 and 5 The opening 5 in spout 2extends up into the head, so that even if the spout is cut through theplane at the base of the head, it will still be open.

The spout 2, which is neck shaped extends through opening 4 so that ifcut on the plane of support a it is ready for operating, by the outletof the fluid contained therein.

Support a is provided with a knife c adapted to decapitate the head 3 asgraphically shown in Figs. 4 and 8.

-In the examples of Figs. 1 to 4 the knife 0 is formed by a cutting edge6 made in V shape in the border of opening 4 so that when grasping theflagon as in Fig. 3 and pulling same outwards, the cutting is donethrough the angular cutting edges separating head 3 from spout 2. Inthis manner the flagon is ready to operate by manually pressing theflexible walls, obtaining the necessary pressure for an effectiveprojection.

In the example of Figs. 5 to 8 the knife 0 constitutes a manuallyactuated member 7 movable in guide 8 and has a digital key 9. Thecutting edge 10 of member 7 is directed towards opening 4, so that whenknife c slides as shown in Fig. 7, the spout 2 is cut separating it fromthe head 3.

Thus the apparatus shown in Fig. 5 in case of emergency is used bytaking hold of the flagon b and pressing on key 9 so that the advancingknife edge 10 decapitates the head 3 and is ready for use as in Fig. 8.

Within the terms of the appended claims, various modifications of detailand structure may be made without departing from the scope or principlesof the invention.

We claim:

1. An emergency fire extinguisher comprising a bag made from flexibleresilient material terminating at one end in an integrally formed neckhaving a relatively narrow passage therethrough, said neck closed by anenlarged resilient button-like integral head and a fixed support forsaid bag having an opening therethrough of such size as to permitpassing said head only when said head is distorted to reduce itsperipheral dimension, the marginal edge of said support surrounding saidopening con stituting a cutting edge whereby said bag is decapitated as,it is pulled from said support to provide a nozzle having a cleanlysevered discharge end for expelling extinguishing liquid in a jetstream.

2. The fire extinguisher of claim 1 wherein said marginal cutting edgesare V-shaped;"

3. An emergency fire-extinguisher comprising a bag made from flexibleresilient material terminating at one endin an integrally formed neckhaving a relatively narrow passage therethrough, said neck closed by anenlarged resilient button-like integral head and a fixed sup- 10 portfor said bag havingan opening therethrough of such sizeas topermit-passing said head only whensaid head i8-1iSiQl'i. Bd to reduceitsperipheral dimension, a knife member slidably supported in guidessecured to said fixed support for movement across said opening andhaving a manual actuating key whereby said bag may be decapitated bypushing on said key to provide a nozzle having a cleanly severeddischarge end for expelling extinguishing liquid in a jet stream.
